What is characteristic of a back-stabbed receptacle?

A back-stabbed receptacle is characterized by the method of connecting the conductors to the receptacle itself. In this type of connection, the conductor is pushed directly into a slot at the back of the receptacle, rather than being attached securely to a screw terminal on the side. This design allows for a quicker and easier installation, as it eliminates the need for a screwdriver to tighten screws. However, it's also important to understand that back-stabbed connections can present potential issues, such as loosening over time or increased resistance, which can lead to overheating.

The other options involve methods of connection that do not apply to back-stabbed receptacles or suggest requirements and characteristics that do not align with their standard design and function. By understanding the unique characteristics of back-stabbed receptacles, one can better appreciate their usage and the safety considerations that come into play with various electrical connection methods.
